Influenza and COVID-19 co-infection and vaccine effectiveness against severe cases: a mathematical modeling study.

Article Synopsis
- - Co-infection of COVID-19 and influenza A can lead to higher mortality and longer hospital stays, indicating an urgent need for studies on their combined impact as seasonal epidemics coexist.
- - An age-specific model was created to analyze how COVID-19 and influenza circulate together, revealing that higher vaccination coverage for both viruses can significantly reduce severe cases, particularly for older individuals.
- - Results show that co-infection leads to a lower transmission rate and delayed peak of SARS-CoV-2, but increases the number of co-infections, emphasizing the importance of simultaneous vaccination to protect vulnerable populations.
Background: The global impact of the coronavirus disease 2019 (COVID-19) pandemic has been profound. Macao Special Administrative Region (SAR), renowned as an international hub for tourism and entertainment, has actively responded to the crisis. However, a comprehensive analysis detailing the evolution of Macao SAR's policies throughout this period is currently lacking.

Specific mitigation strategies are needed to minimize disruption to the healthcare system and to prepare for the next possible epidemic in advance.
Method: We develop a stochastic compartmental model to project the burden on the medical system (that is, the number of fever clinic visits and admission beds) of China after adjustment to COVID-19 policy, which considers the epidemiological characteristics of the Omicron variant, age composition of the population, and vaccine effectiveness against infection and severe COVD-19.
